I would highly recommend this Dr. King's office in Sunnyvale. I had a last minute emergency and his office took me in immediately, even as a new patient. Him and his staff even stayed a bit later to make sure I got the full treatment I needed. The office has very advanced machines that I haven't seen before. Very patient and took the time go thoroughly threw the x-rays and explained to me slowly and patiently what he saw and thought was going on. Dr. Jason Kung quickly assessed my gum infection and calmed my nerves and even gave me a heads up on a potential root canal in the future but said I didn't need it now and to be mindful of certain things in the future. I appreciated his transparency, patience and outstanding hospitality.

The office staff was great they made me feel welcomed and at eased. They answered all my questions (this was my first root canal so I had a lot). The procedure was so smoooth I was in an out with in an hour an half. They did such a great job I would highly recommend coming here if you need a root canal (no pain during or after the procedure).

Dr. Jason Kung has been a huge blessing to my quality of life, and there's no endodontist my family and I trust more. He truly listens to what outcome you want as the patient, then expertly and compassionately delivers it against all odds. His highly skilled work left me and my routine dentist in awe. As a bonus, he speaks fluent English and Mandarin. Details below: 3 other dentists had told me that replacing my teeth with implants was the only way to treat my advanced periodontal disease symptoms (pus and bleeding gums). Unlike most dentists who tried to push me to their desired outcome (very costly implants), what set Dr. Kung apart was how he truly listened to my desired outcome of saving my teeth, made that his goal, and then succeeded in doing that for a very reasonable price. Compared to other dentists, he came up with the simplest and most direct treatment plan (of microsurgery and root canal procedures), and achieved the best results.

Highly Recommend Dr.Kung-I recently needed an apicoectomy (root end surgery) after a previous root canal didn't fully resolve the issue..

Tenía mucho miedo de hacerme un canal de raíz, pero desde que llamé para hacer la cita me di cuenta que estaba en el lugar correcto — el personal habla español y eso me dio mucha tranquilidad desde el principio. Me atendieron rápido, y lo mejor es que tienen horas de fin de semana, algo rarísimo para un especialista — yo trabajo de lunes a viernes y sin esa opción nunca hubiera podido ir. La recepcionista fue muy amable explicándome los detalles del seguro dental. Mi dentista en San Jose me refirió al Dr. Jason Kung en Silicon Valley Endodontics & Microsurgery en Sunnyvale, y fue la mejor recomendación que me pudieron dar. El Dr. Kung es un especialista certificado en endodoncia — usó un microscopio dental y tecnología de imagen avanzada durante todo el procedimiento, y me explicó cada paso con paciencia y claridad. En ningún momento sentí dolor; de hecho, me sorprendió lo tranquilo que fue todo.Todo el equipo fue amabilísimo y profesional; nunca me sentí apurada ni ignorada.

Dr. Kung did an excellent job on my teeth! I had issues with two of my teeth and he fit me in on the weekend. All work was well explained and any questions were answered patiently. The work performed was efficient and painless. I highly recommend Dr. Kung if you are looking for an endodontist for any work on your teeth!

Great experience at Silicon Endodontics. The staff was friendly, professional, and made me feel comfortable throughout the visit. The doctor explained everything clearly and the procedure was quick and smooth. I really appreciated the care and attention to detail—highly recommend!

I had an incredibly good experience at Silicon Valley Endodontists. From the moment I called to the moment I left. People were polite, concerned and considerate. And they were able to provide excellent service on a Sunday afternoon. I was in dire need of pain relief and the Dr did an analysis and performed a root canal. While not the favorite thing I've ever been through, it was relatively easy and without pain. From start to finish I was in and out in 2 hours. And on a Sunday! Thank you Team SVE

Dr. Jason Kung and his team: Tran, Samantha, Ramona and Wai did an AWESOME JOB! Their patience, kindness& supportive professionalism was the best. I'm a huge fan and DEFINITELY RECOMMEND this place for Root Canals, Enndodontics and Microsurgery. They are receptive to anxious patients, like myself. Their follow up the next day check in was thoughtful. I HIGHLY RECOMMEND THIS PLACE! Thank all of you!

Dr. Jason Kung is honestly the best endodontist I've ever been to. I just had a root canal done by him, and the whole experience was shockingly easy. He explained everything he was doing the entire time, checked in constantly, and made sure I was totally comfortable. I didn't feel any pain at all, which blew my mind because I was expecting the worst. Even though I was referred by my dentist, people should know you don't need a referral to see him. He specializes only in root canals -- not general dentistry -- so if you've got an abscess, intense tooth pain, or just know you need a root canal, you can go straight to him and save yourself a lot of stress and time. Dr. Kung is super attentive, patient, and genuinely cares about making sure you're okay throughout the procedure. If you want someone who knows exactly what they're doing and actually makes the whole thing feel easy, he's the one.

What an amazing establishment. I had the pleasure of being referred to Dr. Kung's office by my dentist. Dr. Kung and Jocelyn were phenomenal and so patient oriented. To start, they made a stressful situation fun by allowing me to pick my genre of music for my procedure. Second, Dr.Kung was very friendly, caring, and most important, knowledgeable. He explained each step of my procedure in detail and made sure I was comfortable the whole time. From an administrative standpoint, Dr. Kung and Jocelyn were transparent on pricing, outcome prospects, and how I would feel after the procedure. If you need to see an endodontist, proactively ask your dentist to send you to Silicon Valley Endodontics.

The office was able to get me in asap for a consultation regarding a tooth that needed a specialist review. Dr Kung took the time to explain everything to me and what best options would be. Strongly recommend this office and doctor for anyone looking for a specialist. A++++
